DRYDEN

Every man, says Tully, has two characters; one which he partakes with
all mankind, and by which he is distinguished from brute animals;
another which discriminates him from the rest of his own species, and
impresses on him a manner and temper peculiar to himself; this
particular character, if it be not repugnant to the laws of general
humanity, it is always his business to           and preserve.
